Green MP David Clendon doesn't have a new job lined up when his Parliamentary career ends on September 23 but says he's looking forward to having more time for local environmental causes.
On Monday night Mr Clendon, who lives in Kerikeri, and fellow Green MP Kennedy Graham withdrew from the party list, saying they no longer had confidence in co-leader Metiria Turei.
The party initially threatened to expel the pair but has since agreed they will stay on until the election but won't take part in the campaign.
Mr Clendon said the revelation that Mrs Turei had been enrolled in a different electorate to where she was living, on top of earlier revelations about benefits she received in the 1990s, had prompted his decision.
He believed she should have stepped down and her decision not to seek a ministerial role was "a half way house".
